Therefore, they should not be construed as limiting the scope of protection of this utility model.
[0052] Example 1 provides a row of cutters 1 for a bending machine. The row of cutters 1 is mounted on the bending machine to assist the machine in bending, corner cutting, and stamping operations to prevent the workpiece from losing its locking clips. Figure 1 As shown, the device includes multiple cutting tools 1 and a first connecting member 2. Each pair of adjacent cutting tools 1 are coplanar, and the multiple cutting tools 1 are sequentially connected along a first direction via the first connecting member 2. Preferably, the bottom surfaces of all cutting tools 1 are located on the same horizontal plane.
[0053] Specifically, such as Figure 1As shown, the row of cutters 1 consists of multiple cutters 1 and a first connecting member 2. These cutters 1 are connected sequentially along a specific direction (i.e., the first direction) via the first connecting member 2 to form a row. Each pair of adjacent cutters 1 are arranged coplanarly, with the cutters 1 tightly fitted together, and the bottom surfaces of all cutters 1 are located on the same horizontal plane, so that no breakpoints appear on the workpiece when it is being worked on.
[0054] For reference, in one possible implementation method, such as Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, each of the cutting tools 1 includes a connecting part 13 and a clamping part 14; one end of the connecting part 13 is used to connect with a bending machine, and the other end of the connecting part 13 is connected to the clamping part 14; every two adjacent clamping parts 14 are coplanarly arranged, and each clamping part 14 has a first connecting hole 15 on its side wall. The first connecting member 2 passes through multiple first connecting holes 15 to connect multiple clamping parts 14. The bottom surfaces of adjacent clamping parts 14 are located on the same horizontal plane.
[0055] It should be noted that, as Figure 18 As shown, the bending machine is a common flexible bending machine in the prior art. This application does not improve the flexible bending machine, but only makes structural improvements to the bending cutter 11 used in the flexible bending machine. Therefore, the way the connecting part 1311 of the cutter 11 is connected to the bending machine is existing. For example, the connecting part 1311 can be connected to the corresponding part of the bending machine by bolts, pins or other fasteners.
[0056] The connecting part 13 and the pressing part 14 are integrally formed. In this embodiment, the row of cutting tools 1 can be used in the process of cutting corners on metal sheets, bending metal sheets, and stamping anti-drop buckles on metal sheets. For example, it can be used for cutting corners, bending aluminum panels, and stamping anti-drop buckles on aluminum panels.
[0057] For reference, in one possible implementation, the first connector 2 may be a pin, and the first connecting hole 15 may be a corresponding insertion hole; in another possible implementation, such as... Figure 2 As shown, the first connector 2 includes not only a pin but also a ferrule 21, as... Figure 3 As shown, a slot 141 is provided on the side wall of the connecting part 13, and a first connecting hole 15 is provided on the side wall of the slot 141. The pin passes through the first connecting hole 15, and the insert 21 is inserted into the slot 141 to fix the pin. The size of the insert 21 matches the size of the two slots 141, and a fixing groove is provided in the insert 21. The size of the fixing groove matches the thickness of the pin, and the fixing groove is used to accommodate and fix the pin.
[0058] In one possible implementation, at least one of the plurality of cutting tools 1 has a first forming die core 11 at its bottom, which is used to assist the bending machine in stamping and forming anti-drop buckles on the workpiece.
[0059] Specifically, such as Figure 4 , Figure 5 and Figure 6 As shown. At least one of the plurality of cutting tools 1 has a first groove 16 at the bottom of its clamping part 14. A first upper die 17 is disposed in the first groove 16, and a first forming die core 11 is disposed at the bottom of the first upper die 17. The first forming die core 11 is used to assist the bending machine in stamping and forming anti-drop buckles on the workpiece. In order to ensure that the aluminum single panel can fit tightly against the clamping part 14 when it contacts the surface of the aluminum single panel, the thickness of the first upper die 17 is less than or equal to the depth of the first groove 16. For example, when the thickness of the upper die 17 is equal to the depth of the groove 120, the bottom of the upper die 17 is just flush with the bottom of the groove 120. At this time, the clamping part 1412 can fit tightly against the aluminum single panel.
[0060] In another possible implementation, at least one of the plurality of cutting tools 1 has a second forming die core 12 at its bottom, which is used to assist the bending equipment in completing the corner cutting operation on the workpiece.
[0061] For reference, such as Figure 7 , Figure 8 and Figure 9 As shown, at least one of the plurality of cutting tools 1 has a second groove 18 at the bottom of its clamping part 14. A second upper die 19 is disposed within the second groove 18, and a second forming die core 12 is provided at the bottom of the second upper die 19. The second forming die core 12 is used to assist the bending equipment in completing the corner cutting operation on the workpiece. Similarly, in order to ensure that the aluminum single panel can fit tightly against the clamping part 14 when it contacts the surface of the aluminum single panel, the thickness of the second upper die 19 is less than or equal to the depth of the second groove 18.
[0062] In one possible implementation, taking the connection between the first upper mold 17 and the groove as an example, such as... Figure 10 and Figure 11 As shown, the clamping part 14 has a second connecting hole 142, which communicates with the groove. The top of the first upper mold 17 has a third connecting hole 171, which corresponds to the second connecting hole 142. The second connecting hole 142 and the third connecting hole 171 are connected by a second connector 22.
[0063] In the specific implementation process, taking the connection method between the first upper mold 17 and the groove as an example, such as... Figure 11 As shown, there are six second connecting holes 142, three of which are located on one side of the clamping part 14 and the other three are located on the other side of the clamping part 14. There are also six third connecting holes 171, three of which are located on one side of the first upper mold 17 and the other three are located on the other side of the first upper mold 17.
[0064] The second connector 22 can be a bolt, pin, or other fastener, as in this embodiment, such as... Figure 12 As shown, the connector is a bolt. Both the second connecting hole 142 and the inner wall of the third connecting hole 171 are threaded. The bolt is passed through the second connecting hole 142 on the clamping part 14 and screwed into the third connecting hole 171 on the top of the upper mold, ensuring the upper mold is securely fixed in the groove of the clamping part 14. When the upper mold needs to be replaced, simply unscrew the bolt to easily remove it from the clamping part 14; the replacement process is simple and quick.
[0065] In summary, in this embodiment, by replacing the first upper die 17 or the second upper die 19 at the bottom of each cutter 1 in the row of cutters 1, the row of cutters 1 can have multiple functions beyond assisting bending on a bending machine, such as corner cutting and stamping anti-drop buckles. By integrating bending, corner cutting, and stamping anti-drop buckle functions into the row of cutters 1, multiple processes can be completed in a single machining operation, reducing equipment changeover and workpiece handling time and significantly improving production efficiency. The row of cutters 1 is flexibly designed, and the arrangement and functional configuration of the cutters 1 can be adjusted according to different processing requirements.
[0066] Example 2 provides a multi-functional mold for a bending machine. The mold is installed on the bending machine to assist in bending, corner cutting, and stamping operations to prevent workpieces from falling off, such as... Figure 13 As shown, it includes the row of cutting tools 1 for the bending machine described in Embodiment 1, and also includes the lower die 3, as... Figure 14 and Figure 15 As shown, the top of the lower die 3 is provided with a first forming punch core 31 and a second forming punch core 32. The first forming punch core 31 cooperates with the first forming die to assist the bending equipment in completing the stamping operation to prevent the buckle from falling off the workpiece; the second forming punch core 32 cooperates with the second forming die to assist the bending equipment in completing the corner cutting operation of the workpiece.
[0067] In one possible implementation, to ensure that one side of the aluminum panel remains horizontal when placed on top of the lower mold 3, such as... Figure 16 and Figure 17As shown, the top of the lower mold 3 is provided with a first groove 33 and a second groove 34; the first forming punch core 31 is disposed in the first groove 33, and the height of the first forming punch core 31 is less than or equal to the depth of the first groove 33; the second forming punch core 32 is disposed in the second groove, and the height of the second forming punch core 32 is less than or equal to the depth of the second groove.
[0068] For reference, the bottom of the first forming punch core 31 is connected to a first driving member, which is used to drive the first forming punch core 31 to move toward the first forming die core 11; the bottom of the second forming punch core 32 is connected to a second driving member, which is used to drive the second forming punch core 32 to move toward the second forming die core 12.
[0069] It should be noted that the driving component is a conventional cylinder. The bottom of the first forming punch core 31 is connected to the telescopic end of the cylinder. When the clamping part 14 of the first cutter 1 abuts against one side of the aluminum panel, the cylinder is activated. The cylinder drives the first forming punch core 31 to move toward the first forming concave die core 11 until the first forming concave die core 11 and the first forming punch core 31 are completely closed, and the part of the aluminum panel in the mold cavity is stamped into the shape of the anti-drop buckle.
[0070] The bottom of the second forming punch core 32 is connected to the telescopic end of the cylinder. When the clamping part 14 of the second cutter 1 abuts against the corner of the aluminum panel, the cylinder is activated. The cylinder drives the second forming punch core 32 to move toward the second forming concave die core 12 until the second forming concave die core 12 and the second forming punch core 32 are completely closed, thus completing the corner cutting of the aluminum panel.
[0071] In summary, the forming die cores at the bottom of each cutter 1 in the row of cutters 1 can be replaced according to production needs, and the forming punch cores on the lower die 3 can be changed accordingly. For example, if only bending and corner cutting operations are desired for aluminum panels, only the bottom of the cutters 1 on both sides of the row of cutters 1 needs to be equipped with second forming die cores 12 for corner cutting, and only the second punch cores need to be set on the lower die 3. If only bending and stamping anti-drop buckle operations are desired for aluminum panels, only the bottom of the row of cutters 1 needs to be equipped with stamping anti-drop buckles. The first forming die core 11 is provided, and only the first punch core is provided on the lower die 3. If you want to complete the corner cutting, stamping anti-drop buckle and bending operations of aluminum single panel, you can install the second forming die core 12 for corner cutting on the bottom of the cutter 1 on both sides of the row of cutters 1. Corresponding to the position where you want to stamp anti-drop buckle on aluminum single panel, select the bottom of the corresponding cutter 1 in the row of cutters 1 and install the first forming die core 11 for stamping anti-drop buckle. The second punch core and the first punch core are provided on the lower die 3.
[0072] In this example, taking the operation of chopping corners, stamping anti-drop buckles, and bending of aluminum panels as an example, the aluminum panel is placed on top of the lower mold 3, ensuring that one side of the aluminum panel is aligned with the edge of the lower mold 3. The second cutter 1 (the cutter 1 with the second forming die core 12) in the row of cutters 1 is aligned with the corner of the aluminum panel. The second driving component (cylinder) is activated, and the extension end of the cylinder drives the second forming punch core 32 to move toward the second forming die core 12. When the clamping part 14 of the second cutter 1 abuts against the corner of the aluminum panel, the cylinder continues to push the second forming punch core 32 until the second forming die core 12 and the second forming punch core 32 are completely closed, and the corner of the aluminum panel is cut. After the corner is cut, the cylinder drives the second forming punch core 32 to reset and return to the initial position. The first driving component (cylinder) is activated, and the extension end of the cylinder drives the first forming punch core 31 to move toward the first forming die core 11. When the clamping part 14 of the first cutter 1 abuts against one side of the aluminum panel, the cylinder continues to push the first forming punch core 31 until the first forming concave die core 11 and the first forming punch core 31 are completely closed, stamping the portion of the aluminum panel in the mold cavity into the shape of the anti-drop buckle. After the anti-drop buckle is stamped, the cylinder drives the first forming punch core 31 to reset, and the first forming punch core 31 returns to its initial position. Then, the bending machine controls the row of cutters 1 to separate from the aluminum panel. The bending machine's moving mechanism moves the side of the aluminum panel with the cut corner and the stamped anti-drop buckle to a preset position beyond the edge of the lower die 3. Then, the bending machine lowers the row of cutters 1 to press the aluminum panel tightly, and the bending mechanism of the bending machine bends the side of the aluminum panel beyond the edge of the lower die 3. The above-described embodiments only illustrate specific implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
